Grade 11
Independent & Dependent Events, Tree Diagrams & Contingency Tables
Master the concept of independence vs dependence, tree diagrams with and without replacement, conditional probability, contingency tables with the independence test, and counting outcomes — with full worked examples and exam strategies.
Probability
Master the logic of Tree Diagrams, Dependent events, and Independence tests.
Variance, Standard Deviation & Data Representation
Master the logic of dispersion — why we square deviations, how to calculate variance and standard deviation by hand and from frequency tables, how to read ogives, compare datasets, detect outliers, and interpret skewness — with full worked examples.
Statistics
Understand the logic of histograms, frequency polygons, and standard deviation.
Trigonometric Identities & Equations
Master proving trig identities, solving trig equations with general solutions, and the fundamental identities — with full worked examples.
Sine Rule, Cosine Rule & Area Rule
Master the three rules for non-right-angled triangles — when to use each one, the ambiguous case, 2D problem solving, and full worked examples.
Reduction Formulas, CAST & Co-functions
Master the CAST diagram, every reduction formula, co-functions, negative angles, and how to simplify multi-step trig expressions — with full worked examples.
Trigonometry
Master Reduction Formulas, Identities, and the Sine/Cosine rules for triangles.
The Exponential Graph (Grade 11)
Master exponential growth and decay, the horizontal asymptote, sketching, finding the equation, and understanding why the graph behaves the way it does — with full worked examples.
